Waterbox Aquariums Filter Sock Silencers

Designed to minimize filter sock noise, the Waterbox Sock Silencer dampens splashing sounds while blocking large debris from clogging your filter media. Compatible with 4" and 7" Waterbox filter socks across FRAG, REEF, REEF LX, INFINIA, and MARINE X series tanks, it installs instantly without tools or modifications. Check your model's requirements—some larger systems need two units for optimal performance.
